Application filed September 29, 1904. Serial No. 226,571.

To all whom it may concern;

Be it known that I, Asa ORLANDO W A'lTS, a subject of the King of Great Britain, residing at Windsor Mills, county of Richmond, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Weighing Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in weighing apparatus, designed especially for connection with railway cars, and adapted to weigh that portion of the car supported above the trucks and the contents of the car, or, that portion of the car separately if desired, and consists in certain features of novelty in the construction and arrangement thereof, all as hereinafter more fully described and specifically pointed out in the claims.

The object of the invention is to provide an apparatus of the character indicated, which may be permanently connected with a car, and which will register the approximate weight of the contents of the car automatically as the car is being filled, and the exact weight of the contents of the car by shifting a eight upon the balance beam, as hereinafter described.

Referring to the drawings, in which similar numerals of reference indicate corresponding parts in all the views. Figure 1 is a fragmentary view taken longitudinally of a car showing the middle portion thereof in full lines, with that portion of the car contiguous to the trucks shown in longitudinal section. Fig. 2 is a plan view of the under frame of the car showing at one end, the right, the body bolster supported in position, and at the left the body bolster removed. a transverse sectional view taken approximately 011 line 3-3 of Fig. 2. Fig. 4 is an enlarged detail view showing the end of the balance beam which is supported below the car body, together with the indicating dial and pointer which is used to indicate the weight of the contents of the car. Fig. 5 is an enlarged fragmentary sectional View taken through the car floor, showing one of the intermediate sills and showing the body bolster and truck bolster 1n section with the balance beam held 1n posltion between ap- Fig. 3 is proximately V-shaped members carried by the body bolster and truck bolster.

Referring to the parts, 6 indicates the center sills, which, as shown, extend from end sill 7 to end sill 7 at the opposite end.

8 are the intermediate sills, and 9 are the side sills, while 10 indicates the sheathing commonly used in box car constructions.

11 are the truck bolsters, 12 are the body bolsters, and 13, 13" are approximately V- shaped studs or extensions projecting re spectively upwardly from the truck bolsters at the sides thereof toward the middle por tion of the car, and downwardly from the body bolsters at the sides thereof adjacent to the end sill.

Resting upon the members 13 and below the members 13, are yoke arms 14, which converge between the center sills to levers 15, which meet intermediate the length of the car and approximately at the middle thereof, where said levers are held by a pintle 16, which is carried by the yoke 17, best shown in Fig. 3.

The yoke 17 is connected by the pintle 18 with the transversely extending bar 19, which is c rried at one end in the bifurcated lower end of the hanger 20, which is connected with the floor of the car, or with one of the sills thereof, as may be desired. This bar 19 extends thence toward the opposite side of the car, and preferably terminates between an intermediate sill and a side sill, as shown in the plan view Fig. 2, where a twisted link 21 is pivotally connected with said bar at one end and with the balance beam 22 at its opposite end.

The balance beam 212 is supported in a hanger .13, from which it extends past the link 21, and as shown in Fig. 3, is connected with the coil spring 24, which. spring is wound upon the arbor 25, to which arbor there is attached the indicating pointer 26 cooperating with the scale on the dial 27, which pointer and scale are adapted to register approximately the weight of the car body with its contents.

@ Carried on the balance beam 22, which j beam is serrated at.22, is a balance weight j 29, such as is commonly used on balance beams of scales.

.lt Wlll be observed that the coil spring 24 passes downwardly from the arbor 25 around i the guide roller 30, so that as the beam 2 is lifted in a direction indicated by the arrow in Fig. 4, it will produce a stress in said spring tending to contract the coils thereof, thereby actuating the arbor 25. Such actuation of thearbor shifts the pointer 26 to indicate on its dial 27 the weight supported on levers In the employment of my invention for the purpose of determining the weight of the cargo, or load, of a car, the balance weight 2 9 is adjusted to proper position on the beam 22 to shift the pointer 26 to zero on its dial, under the combined action oi said balance weight 29 and the weight of the car transmitted to the levers 15. The car is then loaded, and the weight of such load will be accurately indicated by the position of the pointer 26 relative to its dial 27.

Cooperating with the balance beam 22 is a spirit level 31, which is connected with said beam by means of the link 32, whereby the said level serves as an indicating means to determine whether or not the balance beam occupies a correct horizontal position. If the beam occupies any other position it may be adjusted by properly shii ting the balance weight 29 on its beam 22.

/Vhile I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed inform or position without a'il'ecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope oi" the following claims, or oi mechanical equivalents to the structures set forth.

Having described my invention, what I claim and desire to secure by Letters Patent is 1. In a railway car, the combination oi a car body, a truck, hearings on said body and truck, levers supported between said bearings, a pivotally supported rod connected to said levers, a balance beam pivotally supported on the car body and connected to said rod, a spring connected to said balance beam, a pointer actuated by said spring, and a graduated dial cooperating with said pointer, substantially as described.

2. In a railway car, a truck bolster, a body bolster, angular hearings on said members, levers supported between said. bearings and. extending thence toward the middle portion of the car, ,a pivotally supported transversely extending rod connected with said levers, a balance beam pivotally connected with the car body and connected intermediate its length with said rod, a spring connected with said balance beam, a pointer actuated by said spring, and a graduated dial over which said pointer is adapted to travel.

In witness whereof I have hereunto set my hand in the presence of two witneses.
